AUTOMATIC FILLING-REPLENISHING LOOM.

Application filed January 11, 1908.

To all whom it may concern:

Be it known that I, ALONZO E. RHOADES, a citizen of the United States, and resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Automatic Filling Replenishing Looms, of which the following description,

in connection with the accom anying drawing, is a specification, like etters on the drawing representing like parts.

This invention relates more particularly to automatic filling-replenishing looms of the type substantially such as forms the subject matter of United States Patent No. 529940, granted to Northrop November 27, 1894, wherein the filling-carriers or bobbins in reserve are contained in a filling-feeder or hopper, to be removed therefrom one by one and inserted in the running shuttle. In such looms the filling-feeder is mounted at one side of the loom, above and in front of the crank-shaft by which motion is imparted to the lay, and at times trouble has been incurred by oil thrown or spattered upon the filling-carriers in the back portion of the fpleder, due to the proximity of the cranks aft.

My present invention has for its object the production of a simple and eflicient oil-guard so arranged as to effectually shield the feeder and the fillingcarriers contained therein from oil thrown from the crank-shaft or adjacent moving parts of the loom, and I have also so constructed the oil-guard that it may be retracted temporarily if the weaver desires to gain convenient access to the back part of the feeder.

Figure 1 is a right hand side elevation of a sufficient portion of a loom provided with filling-replenishing mechanism of the Northrop type, with one embodiment of my invention applied thereto, the outer end-plate 'of the filling-feeder being omitted; Fig. 2 is a rear elevation of the oil-guard and its suport. p Referring to Fig. 1 the crank shaft O hav ing bearings O on the loom sides A one of such bearings being shown, the stand A mounted on the breast-beam at one side of the loom and sustaining a stud a on which is rotatably mounted the filling-feeder, comprising essentially two connected circular plates, only one of which, as a, is shown, said plates holding between them in fixed position by engagement with their ends, a circu- Specification of Letters Patent.

Serial No. 410,335.

I larly arranged series of filling-carriers or bobbins b, and the transferrer f to transfer the latter one by one to the running shuttle,

are and may be all substantially of well i known construction and operation.

The filling-feeder is located above and in front of the crank-shaft, as shown, and at times the yarn on the filling-carriers in the I back and lower portion of the feeder has been injured by oil thrown thereon from the crank-shaft. To obviate this trouble I have arranged an oil-guard to protect the feeder and its contents.

As herein shown a bracket 1 is secured to the loom frame at the replenishing side of the loom, the bracket sustaining rigidly a fulcrum stud 2 extended laterally therefrom behind and near the filling-feeder, a boss 3, Fig. 2, being formed on the bracket.

Upon the stud I pivotally mount a curved, metallic guard 4, shown as rovided with stiffening ribs 5 having hu s 6, Fig. 2, through which the stud extends, and said guard and its ribs may be readily made as a casting.

A collar 7 is pinned to the stud adjacent the inner hub, so that endwise movement of the guard is prevented, the boss 3 abutting against the opposite face of the hub, and a spring 8 is coiled around the stud and se- 1 cured at one end to the guard and at its other end to the collar, as shown in Fig. 2.

The boss 3 is out out to leave limiting shoulders or stops 9, between which plays a pin 10 projecting laterally from the adjacent hub, the spring normally holding the guard in full line position, Fig. 1, adjacent the fillingfeeder, the width of the guard being sufficient to thoroughly protect the filling-carriers in the back and lower portions of the feeder.

Any oil thrown from the crank-shaft or adj acent moving parts of the loom, in the vicinity of the feeder, is caught upon the back of the guard and thereby prevented from touching the filling-carriers.

If the weaver desires to have convenient access to the protected portion of the feeder, to insert or remove a filling-carrier or for any other purpose, he can retract the oil-guard to dotted line position, Fig. 1, the lower shoulder 9 then being engaged by the pin 10, and when the guard is released the spring 8 returns it automatically to normal, operative position, the upper shoulder 9 limiting such forward movement.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a loom, filling-re lenishing mechanism, including a rotata le filling-feeder adapted to contain a supply of filling-carriers and to hold the latter therein in relatively fixed position, and an oil-guard adjacent the rear side of the feeder and movably mounted independently thereof, to protect the filling-carriers in the feeder.

2. In a loom, filling-replenishing mechanism, including a filling-feeder adapted to contain a supply of filling-carriers, a curved, metallic oil-guard adjacent the back and independent of the feeder, and a fixed support for and on which the guard is pivotally mounted, whereby the oil-guard may be retracted from the back of the feeder to permit access thereto.

3. In a loom, filling-replenishing mechanism, including a filling-feeder adapted to contain a supply of filling-carriers, a curved,

metallic oil-guard adjacent the back of the feeder, a fixed support independent of the j feeder and on which the oil-guard is ivotally mounted, and a spring to yielding y maintain the guard in position close to the feeder while permitting it to be retracted temporarily.

4. In a loom, filling-replenishing mechanism, including a rotatable filling-feeder adapted to contain a supply of filling-carriers, a curved, metallic oil-guard adjacent the back of the feeder, to prevent access of oil to the filling-carriers therein, a fixed support on which the guard is pivotally mounted independently of the feeder, a spring to nor mally maintain the guard in operative p0sition while permitting retraction thereof temporarily, and means to limit angular movement of the guard in either direction.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
